TINNING AND RETINNI NG- IKVIAGHIIN'E.

Application filed December 30, 1926.

This invention relates to tinning and retinning machines, more particularly to a carrier for the article to be treated, and has for its object to. provide, in a manner as hereinafter set forth, atravelling carrier for positioning and revolving the article within suitable bath for the coating thereof, and further for disposing the article, after its removal from the bath, in a perpendicular position to provide for the dripping therefrom of any surplus coating.

Further objects of the invention are to provide, in a manner as hereinafter set forth a carrierfor the purpose referred to, which is simple in its construction and arrangement, strong, durable, compact, thoroughly etlicient in its use, and comparatively inexpensive to set up, as well as conveniently installed with respect to the conveyor elementof a tinning or re-tinning or coating machine.

lVith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

ment to provide for the elevating and lower iug of the carrier.

Figure 5 is a rear elevation of thecam element.

Figure 6 is a section 011 line 66 Figure l.

Figure 7 is a fragmentary View, in section illustrating the inner end of the carrier. Referring to the drawings in detail 1 denotes a platform or table, mounted on suitable supports, as indicated at 2. Travelling over the table 1, lengthwise thereof is an endless conveyor 3, only an end portion thereof is shown, and which is in the form of a chain, provided at spaced intervals with yoke-shaped members a, which in connection with pivot pins 5, pivotally connect laterally disposed carriers referred to generally by the reference character 6, to the conveyor 3, so that the carriers 6 will be shifted lengthwise of the table or rather around the top of the table by the conveyor 3. Securedto the table 1 is a pair of longitudinally extending combined guides and supports 7, and each of which is offset as at 8 to set up a supporting means for the conveyor 3. Positioned exterior of the combined guides and supports 7. as well as spaced therefrom, are longitudinally extendingguides 9, of less height than the combined guides-and supports, and these latter in connection with the guides 9 act to guide the members 4:, see Figure 3. The guides 9 are of greater length than the combined guides and supports 7 and project beyond the ends of these latter as shown in Figure 1. Each end of a guide 9 is bevelled as at 10. The guides 9 are of less height'than the height of the combined guides and supports 7. Each yoke shaped member 4 includes a head 11 and a pair of spaced outwardly extending arms 12. The head 11 projects above, below and laterally from the arms 12, and these latter are disposed centrally with respect to the outer face of the head 11. The heads 11 are fixedly secured to the conveyor 3 and the arms 12 are spaced above the top edge of the guides 9.

Secured upon the top 1 is a track member 13 which extends entirely around the conveyor 3, but is spaced outwardly with respect thereto. The track member 13 is formed with low portions lwhich correspond in i ii l inch low part l l only one or which is shown, ot the track 13, is connected to the high part ot the track, by oppositely extending hevelled portions 16, 17. The high part of the track 13 is designed for n'laintaining the 6 in the position shmrn in Figure carrier which is laterally and at an upward inrlination with respect to the table 1. The low portion It of the track, is )ro\ idod for supporting the carrier (3 at right angles with respect to the tahle 1. see Figure 3 and to further provide for the carrier 6 to position the article to he coated within the hath. The low portion .l-.lof the track 13. is of less length than the length ol? the hath, see l ure The position of the carrier 6 when the article heing coated is as shown in Figure 3.

Secured upon the table l. criiteriorly of the low portion 1-1 of the track 13 is a melt 1?, and the function of which will he presentl} referred to. The rack 18 starts at one end in proximity to the entering part at the low portion 'l-l ot the track l'l and has its other end spaced a greater di nce from the other end of the low portion .l oi the track. The rack 18 is ot a length materially less than the length of the bath 15. The teeth of the rack are arranged below the edge of the low portion ll of the track. The function of the rac 18 provides for the revolving or the article 19 to be coated. when the article 19 is lowered into the bath 15 and as the article is moved through the bath a short distance.

Secured to the tahle 1, between the guides 9 and the low part 'l-l oi the track 2h is a cam element 20, of greater height than the high part of the track 13 and also ot greater height than the combined guides and sup ports 7. The element .20 formed with depending peri' ihcrally tl'ireadcd extensions 21 for anchoring it to the table top. The element ill) inchides an inclined surlface a flat surlace 23 at its top, and an inclined surface 22 The inclined surt'ace inclines upwardly and inwardly from its lower end and rearwardly and downwardly from its front. The surfaces 2d inclines downwardly and outwardly with respect to the Hat surface '23. The surface 22 provides means for elerating the carrier (5 to the dotted line posh tion shown in Figure 3 and the surface 2t provides means for restoring the carrier to its inclined position as shown in Figure The carrier 6 includes a shitting block 25, having. bevelled ends 26, 27. The bevelled end 26 coacts with the cam surface 22 for the purpose of elevating the carrier to the dotted line position shown in Figure 3, and when said block 25 rides oil the surface 22, it. is supported upon the surface 23, The surface 24 coacts with the bevelled end 27 for the purpose of restoring the carrier to normal position.

The carrier 6 consists of an lnverted yokeshaped part formed with a pivoted spring controlled arm ill. The other arm ot' the part 28 is lixed and is indicated at All). .lfiach of the arms :3), 230 is normally disposed. rcrtically and carries an in wan-lily erlcndhn hearing ill, at its lower end. The hearing ill, carried by the arm 521i is providcd with a rcrohihle gripper nn-inhcr 23:3. Extended 'l'roni the hearing Ill, curried hr the arm ill] is a I'MUlt'tlllo gripper nleinher 33, which is operated 'lfrrnn a shall Il-l. extending at right angles from the arm Ill) and pro vided on its outer end with a heiclhajl gear 35.

lllf) llll l Ill i Th'e conveyor 3 is operated by pulleys, only one of which is shown, and which are revolubly supported by the table 1, in proximity to each end thereof. The pulley shown is indicated at 48, and has its rim formed with lugs 49 which engage in the conveyor 3, which is of the link typo, therebyfcausing the travel oi the conveyor. The reduced end terminal. 38 of the arm 37, is provided with an opening 50 for the passage of the pivot 5.

It is thought the many advantages of a carrier, as well its o a'erating means, in accordance with this invention, can be readily understood, particularly in view of the fact that it not only provides means for "subjectthe article to be mated, to a bath, but

further provides for the revolving oi the 'article'whil'e it is in the bath, and then furtherinore it acts to elevate the ai 'cle to perpendicular position so that the surplus coatiiigcan drip therefrom, and although the preferred embodiment otthe invention is as illustrated and described, yet it is to be understood that changes in the details oi? construction can be had which will fall within the stops of the invention as claimed.
